Dynamic, 3D pattern formation within protein-based gel

Modern regenerative medicine is on the lookout for implantable materials that can change as the surrounding tissue does, and two Stanford University researchers have made some new gel materials that do just that. Karin Straley and Professor Sarah Heilshorn have developed a method for preparing protein-based implant materials that can evolve with the changing needs of the host biological system. Not only can their new materials change in different ways at different times, they can do so at different places within the implant materials.

Scientists re-engineer human enzyme to become resistant to harmful agents such as chemotherapy

Scientists from the Université de Montréal and McGill University have re-engineered a human enzyme, a protein that accelerates chemical reactions within the human body, to become highly resistant to harmful agents such as chemotherapy, according to a new study published in The Journal of Biological Chemistry.

Current diagnostic tests for ovarian cancer woefully ineffective

A new study finds that in order to make a significant dent in the mortality rate for the deadly cancer, the tests would have to be able to detect tumors of less than 1 cm in diameter, or about 200-times smaller in mass than those currently used to assess potential new tests. Still, if that hurdle can be overcome, there is good reason to believe that testing could make a big difference: The window of opportunity for treating these clinically undetectable cancers before they become life threatening is surprisingly long: about four years.

Discovery of key event in prostate cancer progression

A study led by researchers at the Ohio State University Comprehensive Cancer Center and Dana-Farber Cancer Institute reveals how late-stage, hormone-independent prostate tumors gain the ability to grow without need of hormones.

New discovery on DNA repair mechanism

Researchers at Washington University School of Medicine in St. Louis have shed new light on a process that fixes breaks in the genetic material of the body's cells. Their findings could lead to ways of enhancing chemotherapy drugs that destroy cancer cells by damaging their DNA.

New perspectives in the treatment of disease

The team, led by Professor Matthias Mann of Novo Nordisk Center for Protein Research at the University of Copenhagen and the Max Planck Institute for Biochemistry in Germany, have detected 3,600 acetylation switches in 1,750 different proteins.

Carnosine may help prevent, treat cataracts

Researchers are reporting evidence from tissue culture experiments that the popular dietary supplement carnosine may help to prevent and treat cataracts, a clouding of the lens of the eye that is a leading cause of vision loss worldwide.

Discovery of key protein for tumor suppression in ER+ breast cancer

Researchers from the Kimmel Cancer Center at Jefferson have identified a protein relationship that may be an ideal treatment target for ER+ breast cancer. The study was reported in the July 15 issue of Cancer Research.

Special pathway makes bacteria vulnerable - new target for tailored antibiotics

More and more strains of bacteria are developing resistance to previously life-saving antibiotics. Researchers at TUM, the Technische Universitaet Muenchen, have shed light on a metabolic step that appears in many aggressive microorganisms -- such as tuberculosis and malaria pathogens -- and that may provide a promising target for a new class of antibiotics. The researchers present their results in the chemistry journal Angewandte Chemie.

Research may hold key to maintaining embryonic stem cells in lab

In a new study that could transform embryonic stem cell (ES cell) research, scientists at UT Southwestern Medical Center have discovered why mouse ES cells can be easily grown in a laboratory while other mammalian ES cells are difficult, if not impossible, to maintain.

A new prostate cancer "homing device" for drug delivery

A new prostate cancer "homing device" could improve detection and allow for the first targeted treatment of the disease. A team of Purdue University researchers has synthesized a molecule that finds and penetrates prostate cancer cells and has created imaging agents and therapeutic drugs that can link to the molecule and be carried with it as cargo.

Specially bred purple sweet potato with anti-cancer components

A Kansas State University researcher is studying the potential health benefits of a specially bred purple sweet potato because its dominant purple color results in an increased amount of anti-cancer components.

“Life force” linked to body’s ability to withstand stress

Our ability to withstand stress-related, inflammatory diseases may be associated, not just with our race and sex, but with our personality as well, according to a study published in the July issue of the journal Brain, Behavior and Immunity. Especially in aging women, low levels of the personality trait extraversion may indicate that blood levels of a key inflammatory molecule have crossed over a threshold linked to a doubling of risk of death within five years.
